V Application filed December irllvla Serial No.335,0 73. (No model.)

i Beit known that I, JOSEPH B'. BALLARD, re-V siding at Ballardsville, inthe county of Itawamba and State of) Mississippi, have InT Avented certain newand 'nset'nl Improvements in Combined Dust-Guard vand Ventilator for Car-"Windows, ofwhich' the -following 1s a specification.'v p Y My invention has for Its object to provide a suitable attachment for carwindows whichv will prevent-the smoke, dust,and clnders passing into the cars while being ventilated, and

- also Vto prevent the passage of very strong cnr- -rents of air into the' car during motion while thel window is raised.l v

To thisend 'my invention. consists lnjcerfl tain novel features of construction and peculiar combination ot'v parts, all of -wlnch will hereinafter be fully described in the annexed specification and particnlarly pointedoutin the claims, reference being had to the accompanying drawings, in wh1ch- Figure 1 is a perspective View of 4my 1inprovement as appliedto a car-window. Fig; 2 is a vertical section taken onthe line 2, Fig. '1. Fig. 3 is a horizontal sectional view of the device. Fig.' 4 is a detailsection on the line 4 4, Fig. 3; and Figs; 5 and Gare detail views hereinafter specificallyreferredA to. Y

In the accompanying drawings, A'Ind-icates a frame of suicient width and length to fit the window and extend as high as the bottom vof the upper sash, or of such length as .may

be deemedv best for the particular kind of window with which' .it may be nsed. This frame, which is formed of the upper and lower transversestrips a a and the slde pieces b b, is placed as near the outside of the car-window as possible, and so placed as to be capable of being raised when necessary. To this end I adjust the side pieces b b 'between cleats b b of the window-frame.

c denotes an inwardly-projectlng strlpsecured upon the upper edge of the upper crosspiece a, which extends. close up to the upper sash, so as to prevent cInders from falling between the said frame and the car-wlndow.

It is obvious that in case my Improved combined dust-excluder and ventilator I s used In place of the" lower sash, as in some Instances it may be found preferable to so construct It, the strip C may be dispensed with.

` B denotes the window portion of the frame A, 'which is formed of a series of transparent slats B, preferably glass, all of which, except the end ones B2 B2, "are pivotally supported in the'upper andlower cross-pieces a a', as most l"clearly shown in Figs. 3 and 4 'ofthe drawings, so as to readily admit of their being v opened and closed in a manner well understood, such pivoted slats and the'end slats being so arranged'that when they are closed in theywill lap eachother, so aste' prevent dust or cinders passing between them. The pivotal slats are of suchwidth that when they are turned edgowise theywill project beyond the edgeof the'cross-peces a'ja,so'as to perslat, and with an extension e2, which fts'the 'cut-away part llvof the slat, said plates being secured in. place by passing rivets through the wings e andthe slats, said plates E having pintles 12, which engage 'thecross-pieces :a a', as shown. Y p 'l By thus securing the pivot-plates to the mit of their convenient connection to the operatingilever D, such connection being preferably made vas shown in Figs.l 4 `and 5 of the drawings, from whiclrit will beobserved that slats I am enabled to make a strong connec tion therewith when they are made of glass. The outer ends of the extensions e2 of the lower set ofplatesE E are formed with .apertured ears es e3, which are pivotally connected with a series of 'apertnredlngs ff, projected inward from the reciprocating operating -leverl D, which is supported on an inwardly-projecting plate G, secured upon the cross-piece 0, of the frame, snchvbarbeing capable ofbeing locked in any portion of its movement on said plate by means 4of a suitable locking device, most clearly shown iniFigf. 6 ot'4 the drawings, Aby reference tolwhich it will be seen that I provide the plate Gr.with a segmental slot g and the bar with a downwardly-projecting bolt d,

which projects through said vslot and is pro- IOO the bottoni of said socket. I also form the` said head d only half-round and bevel the top,l as shown std, and in the upper end of said socket is inserted, to turn` therein, an

operating-button H, the shank portionh of which is formed with a semicircularprojection h', having its lower end beveled at h, such projected portion adapted, when the knob is turned in either direction, to engage and depress the'sprin bolt d', and thereby release itslower head from frictional con tact `with theplateG and permit the slidesto be opened to any desired extent, and when in such po,s`iti on,"by simply turning the knob slightly in atreverse direction, the bolt d will lock theparts in itlierdesired position. To make a goed frictinalcontact'l roughen the lower edge of the plate Gand the upper edge of the head d2, asshown.' i"

Frein the [foregoing'deseriptiomtaken in connection with the drawings, theadvantages of my improvementv will readily appear. It f,

will be observed that the same is exceedingly simple in construction and operation, can be made atfa very small cost, and be readily adjusted to car-windows of ordinary construction.

Having thus described my inventiomhwhatl claim, and desire to secure by Letters Patent,

1. The coinbination, with the main frame A, composed of the cross-pieces a a', the side strips b b, andthe inwardly-projecting strip c, secured upon thelingier side of Vthe upper cross-piece a, -said frame adapted for vertical adjustment on the windowframe outside the lower sash, of the fixed end slats B2 and the intermediate pivotal slats B', said slats B B2 adapted td lap each other when folded to gether, substantially as and for theypurpose described. y

2. The con1bination,with the frame A, formed of the side and end pieces a a b b, and the slats B', formed with notches l0 and eut-away portions 11 in their ends, of the pivotal plates E E', formed with winged portions e, lapping the ends ofthe slats B enlarged portions e e2, fitting the notches 10 and cut-away portions 11, and the pintles l2, adapted to engage the cross-'pieces a a',=all arranged subsmntially as and for Kthe purpose described.

3. The combination, with the frame A, formed of the side and end pieces a a .1g b, the

,slats B', formed of transparent material, a'nd the pivotal plates EE', secured upon the ends of said slats B', the lower plates E provided with ears es e', of the operatin -lever D, ypro: videdwith a series of lugs pivotally secured to said ears, whereby the oscillation of said lever will open or close said slats, and locking devices for holding said lever in adjusted positions, substantially as shown and described.

' 4. The combination, with the frame A, consisting of the sidepieces bb and thecross-pieces a a', the lower cross-piece having a horizon tally-disposed inwardly-extended plate G, ro'- vided with a segmental slot, ofthe slats B B', pivoted in the cross-pieces o ai, the lower ends of said slats having lateral ears ea e3, the Voperating-lever D, provided with inwardly'extending lugs ff, pivotally connected to said ears e3 e, and a locking device for holding said lever in'adjusted positions, consisting of a vertically-adjustable bolt projected from` said lever through said segmental slot, having an enlarged head normally engaging the lower face of said projection, the upper end of said bolt operating in a recess insaid lever and having a semicircular beveled head, a springinterposed between said beveled head and the base of the recess, and an unlockingbutton I'I. having a semicircular beveledextension h', adapted when turned to engage and depress the bolt, all arranged substantially as and for the purpose described.
